A DC-to-DC voltage convertor is made up of a capacitor array having plural capacitor elements (Cp1, Cp2, Cp3) and a plurality of switches (S2...S10) which are switchable between at least two states. When the switches are switched in the first state, the capacitor elements are connected in series, and when the switches are connected in the second state, the capacitor elements are connected in parallel. The DC-to-DC voltage convertor may be configured as a step-down converter (Fig. 2a) or a step-up converter (Fig. 2b).
